Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators examine about the efficacy of field-of-regard-focused visual exploration therapy implemented using a head-mounted display virtual reality system for hemispatial neglect rehabilitation following stroke.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

19 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  • presence of left hemispatial neglect as demonstrated by a score above the cut-off on the line bisection test or star cancellation test of the Behavioral Inattention Test, or mild-to-moderate neglect-related functional impairment defined by a score of 1-20 points on the Catherine Bergego Scale
  • age 19 to 65 years
  • first-time right hemispheric ischemic or haemorrhagic stroke as evidenced by brain imaging and medical records

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Field of regard-response time
Time Frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
time interval between target onset and response with field of regard setting
Baseline, 4 weeks from baseline, 8 weeks from baseline
Change in Field of regard-success rate
Time Frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
percentage of correct responses (clicking the left or right mouse button in response to a blue or red target, respectively) with field of regard setting
Baseline, 4 weeks from baseline, 8 weeks from baseline
Change in Field of regard-head movement
Time Frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
sum of all quantified head-rotations with field of regard setting
Baseline, 4 weeks from baseline, 8 weeks from baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Field of view-response time
Time Frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
time interval between target onset and response with field of view setting
Baseline, 4 weeks from baseline, 8 weeks from baseline
Field of view-success rate
Time Frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
percentage of correct responses (clicking the left or right mouse button in response to a blue or red target, respectively) with field of view setting
Baseline, 4 weeks from baseline, 8 weeks from baseline
Line bisection test
Time Frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
Participants were asked to bisect the given lines by marking the centre of each line using their preferred or unaffected hand
Baseline, 4 weeks from baseline, 8 weeks from baseline
Star cancellation test
Time Frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
The experimenter crossed out the two small, central stars of the sheet as an example, following which participants were asked to mark the remaining small stars.
Baseline, 4 weeks from baseline, 8 weeks from baseline
Catherine Bergego Scale
Time Frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
